Fix workflow matrix to invoke correct Gradle test tasks

The workflow was calling non-existent tasks testStandardDebugShard1-4,
but the Gradle build defines testShard1Vault, testShard2Platform,
testShard3Auth, and testShard4Data. Added matrix.include mapping to
resolve task names correctly and enable fail-fast: false for resilience.
